“I didn’t know plain white T-shirts were bad - is that a gang thang?”
Plain white T-shirts are undergarments. People should know better than to go to a restaurant in their underwear.
Plain white T-shirts are undergarments.
Really? Says who? Is a blue one or a black one okay. Why?
I would say that a plain white t-shirt is preferable to the logo tees that a lot of people wear, with various offensive slogans and pictures on them.
Also, while I don’t actually have a white one, I have plain tees in a variety of colours - white is available - that definitely aren’t undershirts. Difficult to write rules that could differentiate between the two, though.
